I have bought many of these for my 1991 bost over the years. This is the first one that has NOT included the required gasket. What do I do now that I need the gasket? I bought 2 of these to save on future shipping. Vendors should not sell parts without the required gaskets in order to have happy customers!

I bought this kit to repair a Sherwood model R991 pump. To my dismay, it did NOT come with the rubber O-ring that seals the cover to the pump housing. I had to purchase the O-ring from another store to complete the repair. The gaskets shown in the picture do NOT fit a Sherwood model R991.

The impeller worked great and very satisfied with iboats. I will use them again for my future boating needs.

Works perfectlyby John from Lizella, Georgia on June 19, 2011

Double check the model number on your water pump and don't just go off the engine. Seems most people are unhappy because that's what they did. You have to pull the pump off anyway... Anyway, this impeller was a perfect fit and the o-ring that came was good as well. Also love how fast iBoats ships stuff!

non volvo impellers bewareby Robert from Livingston, California on August 16, 2012

Never again will I substitute another brand impeller to save money.This inferior product never made it to the water.When I started the engine WITH WATER HOOKED UP the impeller housing reached 300 F.After replacing the old VOLVO impeller it ran at 72F.This was an expensive lesson.

Kit had wrong o-ring...tried to get just O-ring replacement, but Sierra doesn't make thus, iboats said I need to return old kit, and get a new kit. But, new kit still has wrong 0-ring, so how is that correcting my probem? Even thought Sierra made mistake with wrong O-ring in kit, Iboats wouldn't fix problem by send me a correct OEM o-ring. I had to buy $2 part. My advice...forget Sierra and Iboat combo spent the extra $ and buy OEM. This would have saved me hours of headach.

Looks good but time will tell.by Bobby from Huntsville, Alabama on February 08, 2012

This is going on a 1999 VP SX. The size/length of the paddles are identical to the OEM VP part I had in last year. The O-ring for the pump is just a hair big but went together just fine. I did notice the brass splined section of the impeller was actually longer than the OEM piece and made more contact on the shaft of the pump. Looks like a good thing to me. My 1 season old VP impeller was missing 2 and 1/2 of the paddles(~50 hours) Ill post up the results from this impeller at the end of the 2012 season. Gave it a 4 based on o-ring size.

works as advertisedby John from Seattle, Washington on November 25, 2011

I have been using these impellers for six years it is the right product at the right price. The impeller maintains it pliability so well that I now change it out every other year as opposed to annually in my 1995 220VRS Matercraft.

Q:

I'm showing part number SP 685007 for my impeller on a 2005 Tige 22i Marine Power 5.7L, 350 hp, EFI will the 18-3020 work?

A:

It looks like the Marine Power used Johnson 09-812B pump which means you would need 18-3306 (dimater 2-1/4", side with 1-15/16"): http://www.iboats.com/Neoprene-Water-Pump-Impeller-18-3306-Sierra/dm/view_id.174178
